We just learned about the Milling Cutter.

One type of milling cutter is called a Hob.
Cutting with a hob is called hobbing.

When you need to make a gear or sprocket to be used in a machine or something like a bike chain, the hob can be used to cut the teeth of the gear into the right size and shape.
